Initially geometric, using circles as well as the two point arch, it derived from the French Rayonnant style. However, it slowly became more daring and flowing; the name curvilinear has been ascribed to it. Windows became larger, increasing the number of mullions (the vertical bars dividing the main part of the window) between the lights; above them, within the arch of the window, the tracery was formed using shapes styled 'daggers' and 'mouchettes',"
"Muntin A muntin (US), muntin bar, glazing bar (UK) or sash bar is a strip of wood or metal separating and holding panes of glass in a window. Muntins can be found in doors, windows and furniture, typically in western styles of architecture.

"one large sheet of glass per sash, while windows in the past were glazed with multiple panes separated by ""glazing bars"", or ""muntins"", due to the unavailability of large sheets of glass. Today, glazing bars tend to be decorative, separating windows into small panes of glass even though larger panes of glass are available, generally in a pattern dictated by the architectural style at use. Glazing bars are typically wooden, but occasionally lead glazing bars soldered in place are used for more intricate glazing patterns. Many windows have movable window coverings such as blinds or curtains to keep out light,"

Mullion A mullion is a vertical or horizontal element that forms a division between units of a window or screen, or is used decoratively. When dividing adjacent window units its primary purpose is a rigid support to the glazing of the window. Its secondary purpose is to provide structural support to an arch or lintel above the window opening. Horizontal elements separating the head of a door from a window above are both a head jamb and horizontal mullion and are called ""transoms"". Stone mullions were used"
"Window decoration In graphical user interfaces, the window decoration is a part of a window in most windowing systems. A windows decoration typically consists of a title bar, usually along the top of each window and a minimal border around the other three sides. On Microsoft Windows this is called ""nonclient area"". In the predominant layout for modern window decorations, the top bar contains the title of that window and buttons which perform windowing-related actions such as: The border exists primarily to allow the user to resize the window, but also to create a visual separation between the window's contents"

A cross-window is a rectangular window usually divided into four lights by a mullion and transom that form a Latin cross. The term eyebrow window is used in two ways: a curved top window in a wall or in an eyebrow dormer; and a row of small windows usually under the front eaves such as the James-Lorah House in Pennsylvania.

Typically, the cellular window is used for an attic or as a decorative feature, but it can also be a major architectural element to provide the natural lighting inside buildings.

A multi-lite window is a window glazed with small panes of glass separated by wooden or lead ""glazing bars"", or ""muntins"", arranged in a decorative ""glazing pattern"" often dictated by the building's architectural style. Due to the historic unavailability of large panes of glass, the multi-lit (or ""lattice window"") was the most common window style until the beginning of the 20th century, and is still used in traditional architecture.

This contrasts with a mullion, a ""vertical"" structural member. Transom or transom window is also the customary U.S. word used for a transom light, the window over this crosspiece. In Britain, the transom light is usually referred to as a ""fanlight"", often with a semi-circular shape, especially when the window is segmented like the slats of a folding hand fan.

They were originally rather crude constructions consisting merely of a barrel. Later they evolved into more elaborate designs made of"
